A Plan to Replenish the Colorado River Could Mean Dry Alfalfa Fields. And Many Farmers are for it

A plan to help shore up the depleted Colorado River by cutting off water to alfalfa fields in California’s crop-rich Imperial Valley is finding support from the farmers who grow it.

The Imperial Irrigation District — the biggest user of water from the 1,450-mile (2,334-kilometer) river — has offered to pay farmers to shut off irrigation to forage crops including alfalfa for up to 60 days during the peak of the sweltering summer. While farmers often balk at the idea of letting fields lie fallow, at least 80% of properties eligible for the new program have been signed up to participate, said Tina Shields, the district’s water department manager.
